Title: Piezoelectric porcelain
Inventor: YONEZAWA MASATOMO
IPC: H01L41/187
Filed: 1981-02-12
Abstract: PURPOSE:To obtain a piezoelectric porcelain having a high performance and a mass productivity by combining x, y and z in KxNayLizNbO3 (x+y+z=1) within a certain range, and ading 0.05-0.5mol% of MnO as a by-product component. CONSTITUTION:After weighing and mixing powders of K2CO3, Na2CO3, Nb2O3, Li2CO3 and MnCO3 to a given amount those are sintered to form a solid solution of KNbO3-NaNbO3-LiNbO3. When this composition is shown by KxNayLizNbO3 (x+ y+z=1) defining a total value of x, y and z within the above range and further a certain amount of MnO is added therein as a subcomponent, the dielectric constant decreases more by keeping low the value of the mechanical quality constant as a vibrator, and a electric mechanical coupling factor increases in the diameter direction, thereby being able to obtain a piezoelectric porcelain having a low dispersion.  Furthermore, the effect of MnO2 is low in case of less than 0.05mol%, while an  uniform porcelain is not obtained in case of more than 0.5mol%.

Title: Head positioning servo mechanism of magnetic disk device
Inventor: SUGIMOTO YUKIMASA
IPC: G11B5/596
Filed: 1983-02-09
Abstract: PURPOSE:To always secure actuation of the said servo mechanism regardless of a speed control mode or a position control mode by amplifying the error obtained by subtracting the current estimating signal from the current detecting signal and adding the disturbance eliminating signal to the input of a power amplifier. CONSTITUTION:The acceleration of a servo motor is proportional to the current when no disturbance exists. It is considered that the disturbance exists if said proportion is not obtained. Therefore the disturbance is eliminated by adding a current proportional to the error to the motor. A loop which is applied to a power amplifier 1 from an error amplifier 9 via a gain matching element 10 actuates only to the disturbance which disturbs the main control. The difference between the current detecting signal J1 and the current estimating signal J0 is zero in an ideal state where no disturbance exists. Then the disturbance eliminating signal which is added to the amplifier 1 from the amplifier 9 via the element 10 is also zero. The block of a differentiating circuit 8, the amplifier 9 and the element 10 gives no effect to the main control at all. If the disturbance exists, a difference is produced between signals J1 and J0. Then the disturbance eliminating signal is produced to the output of the amplifier 9 and added to the input of the amplifier 1. Thus the main control signal E receives no effect of disturbance.
